Section 1: General Safety Instructions
1.1 Intended Use
The Bettis SCE300 electric actuator is designed to operate any type of quarter-turn
industrial valve (e.g. ball, buttery, plug, control) used in a wide range of applications.
Such applications range from heavy industrial (e.g. chemical, petrochemical plants,
waterworks, water pipelines, waste paper plants) to commercial (e.g. food, brewing,
heating, ventilation, air conditioning).
Emerson will not be liable for potential or actual damage or physical injury resulting from
use in other than the designated applications or by a lack of care during installation,
operation, adjustment, and maintenance of the machine. Such risks lie entirely with
the user. Depending on the specic working conditions, additional precautions may
be requested. Given that Emerson has no direct control over particular applications,
operation, or maintenance conditions, it is the operator's responsibility to comply with all
applicable safety rules.
Inform Emerson as a matter of urgency if you face unsafe situations not described in this
IOM. It is the sole responsibility of the operator to ensure that local health and safety
regulations are adhered to. The SCE300 is tested according to UNI EN ISO 1680. Noise level
is less than 65 dB (grade A) at 1 m distance.
WARNING
Installation, conguration, commissioning, maintenance, and repairs must be performed
by approved and qualied personnel only.
The SCE300 electric actuator is designed in accordance with the applicable international
rules and specications, but the following regulations must nonetheless be observed:
• General and safety regulations
• Plant-specic regulations and requirements
• The proper use of personal and protective devices (glasses, clothing, gloves, etc.)
• The proper use of tools, lifting equipment, and transport equipment
• Electrical installation, use, and maintenance of the SCE300 must be conducted in
accordance with the national legislation and statutory requirements related to the
safe use of such an actuator (as applicable to the site of installation)
• Contact Emerson should further information and/or guidance regarding safe use
of the SCE300 actuator be required.
CAUTION
The SCE300 contains parts and sub-assemblies susceptible to damage from electrostatic
discharge (ESD). Before performing any type of work on the actuator, use ESD protection
or discharge static electricity by providing physical contact to grounded metal.

1.4.2 Explosion-Proof Version
The version of the SCE300 suitable for installation in hazardous areas is designed and
manufactured according to EN 60079-0, EN 60079-1, EN IEC 60079-7, EN 60079-3 standards.
Different types of protection are available, depending on the requirements of the
installation site.
The driven valve or associated gear reducer will form part of a separate risk analysis in
accordance with Directive 2014/34/EU ,and follows the EN ISO 80079-36 and
EN ISO 80079-37 norms.
Specic types of protection are printed on the label, as follows:
• ATEX Ex de IIB T5 with enclosures in explosion-proof version and terminal board
enclosure in increased safety version
• FM rated as ame-proof for Class I, Zone 1, Group IIB , T5; Class II, III, Div. 1,
Groups E, F and G, T4
• NEMA 7 and NEMA 9
The above versions of the SCE300 prevent the risk of explosion in the presence of gas or
ignitable dusts. The SCE300 actuator possesses IP66/68 degree of protection in
accordance with EN 60529.
WARNING
When installing the actuator in a hazardous area (as dened by the applicable rules), refer
to the actuator nameplate to verify that certication, approval, and protections conform to
site safety requirements.
WARNING
Installation, conguration, commissioning, maintenance, and repairs must be performed by
approved and qualied personnel only.
